To specify automatic failover configuration settings:

1. Go to the **Settings** icon > **Setup** > **Failover Configuration** tab.  
The Failover Configuration page appears, listing all device interfaces that are used by the system.
2. On the **Failover Configuration** page, complete the following:
  - **Virtual IP address**: Enter the VIP address.
  - **Connection Mode**: Select the connection mode from the drop-down list. You can select **Direct** if the systems are connected directly through the HA port or select **Network** if the HA port of both systems are connected to a network. Infoblox recommends that you use the **Direct** connection mode.
  - **Virtual Hostname**: Enter the hostname for the system.
  - **Port**: Enter the TCP port for replication traffic, if you are using Network connection mode. You must enter a port number great than 1024.  
  
In the **Replication** **Nodes** section, enter the following for both **Primary** and **Secondary**.
  - **Role**: Displays the role of the appliance, either **PRIMARY** or **SECONDARY**.
  - **Management**** IP**: Enter the management IP address of the system.
  - **Hostname**: Enter the hostname of the system.
  - **Replication ****IP**: Enter the IP address used for replication traffic, if you are using **Network** connection mode.
  - **Subnet**: Enter the subnet mask of the replication IP, if you are using **Network** connection mode. Note that the subnet mask must be the same for both primary and secondary appliances.
3. Click **Update** to update the settings and replicate data on both the primary and secondary appliances.
4. Click **Enable** to start connecting the systems. Establishing an HA connection between virtual appliances requires a reboot but establishing an HA connection between hardware appliances does not.

The secondary system synchronizes data with the primary system. This process might take about one hour, depending on the appliance model.
